(CNN) – The verbal back-and-forth between former Delaware Senate candidate Christine O'Donnell and Citizens for Responsibility and Ethics (CREW) continued Wednesday as O'Donnell made her case for why the group should lose its nonprofit status as a 501(c)3.

"We're fighting back because while I'm certainly not the first person they've come after, I would like to be the last," O'Donnell said on a conference call with reporters. "I would like to stop this."FULL POST

Citizens for Responsibility and Ethics in Washington filed complaints with the Delaware U.S. Attorney's Office and the Federal Election Commission against O'Donnell, charging that more than $20,000 of O'Donnell's spending in 2009 and 2010 was illegal because O'Donnell was no longer a candidate.
